As a tao u can pre hit the guys whilst in mid dash u just need to time it correct after the 2nd step of the dash, still bit of a joke seeing as sd/autorun/bc all blend together so its pretty hard to actually tell when they started the dash.
To even be able to land the hit is a job in itself and even with landing the hit , most warriors have 500%+ hpr and lets just say i would luckily hit a 1k boreal on the minimal chance i could , 1 dash and hes regend everything whilst being impervious to all damage apart from the tiny time window during that dash and at the end of the dash.
I saw threads of having a war skill where u turn to stone and become invincible.... u already have this skill in shoulder dash lol.
i dont agree with most wars have 500%HPR lol rarely a warrior got more than 400 ....and your boreals do up to 2 k damage not just 1k as you said
